UC2845D Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 12V~28V and has a 12V~28V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. The switching controller is capable of switching at the 500kHz position. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Frequency Control is included in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 14 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. It is recommended that the dc dc voltage regulator's minimum input voltage be 8.2V. DC regulator outputs 2.5V voltage based on test statistics. The dc to dc regulator can only accept 25V input voltage. A value of 1A is output as the maximum value of current.
